Abstract
A magnetic head assembly comprises a carriage on which a first magnetic head is mounted for performing read/write with respect to one face of a disk, a second magnetic head also mounted on the carriage opposite to the first magnetic head for performing read/write with respect to the other face of the disk, and a hold case coupled turnably via a leaf hinge spring to the carriage, wherein the first magnetic head is attached via a gimbal spring to the carriage, and the second magnetic head is secured to the hold case, and is characterized in that the carriage has a support portion abutting directly on the hold case inclusive of the leaf hinge spring to support the same, so that the hold case is supported turnably with the support portion serving as a supporting point, whereby the reference plane of the hold case is defined by the support portion, so that accuracy can be ensured for the reference plane of the second magnetic head with respect to the disk and an enhancement of the follow-up performance can contribute to an improvement of the read/write characteristic.
